Title: Method and apparatus for molding
Inventor: FUJISAWA KOJI
IPC: B29C33/18
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent a residue of a gas in a cavity in a molding apparatus for injection molding in a state in which a film is sandwiched between molds. SOLUTION: A method for molding comprises the steps of opening molds (S101), sending a film F, closely contacting the film F with a recess 12, then closing the molds (S104), starting exhausting of a cavity 22 (S105), and then injecting a resin in the cavity 22. The method further comprises the steps of stopping exhausting of the cavity 22 (S107), waiting a solidification of the resin (S108), opening the molds (S101), and then taking out a molding. Since the cavity 22 is exhausted before the injection and then the exhausting is also conducted parallel to the injection, the air in the cavity 22 and the gas generated from a resin can be satisfactorily exhausted. The gas is not retained when the resin is filled in the cavity 22, and a harm by the gas retained in the cavity 22 can be prevented.
